Checklist of the Pachyrhynchus Germar, 1824 (Coleoptera: Curculionidae: Pachyrhynchini) species, available from HUF collections (Hungarian Museum of the Natural History) is presented. Collection comprises a total of 31 Pachyrhynchus species and 5 subspecies. One new species from the Mindanao Island was found during the observation, species in general appearance is similar to P. amabilis Schultze, 1922 (see differential analyses), this new species is described herein. Photos of the habitus, as well as pictures of male and female genitalia are presented.

Key words: HUF, Pachyrhynchini, Pachyrhynchus, Mindanao, taxonomy, new species.

INTRODUCTION additional distributional information of various species (Rukmane 2019). As for Pachyrhynchus Knowledge on the genus Pachyrhynchus Germar, species collection of the Hungarian Museum of 1824 has went far beyond in past few years, as the Natural History, 31 species was determined many foreign and local scientists has contributed and are listed herein, moreover, one species were to taxonomy, ecology and distribution (Cabras identified as new to science. Here I provide a list & Rukmane 2016, Rukmane & Barševskis of the species from the HUF. 2016). As this particular genus is admitted to be highly commercial, it is widely present among Pachyrhynchus amabilis species group currently various museum collections. Observation of comprises 7 species, distributed on various the old museum collections can reveal new data parts of the Mindanao Island: P. amabilis on taxonomy and biogeography of the current Schultze, 1922; P. banglas Bollino, Sandel & genus, such example are some previous works of Rukmane, 2018; P. chamissoi Schultze, 1922; P. the author, which presents few new species and pseudamabilis Yoshitake, 2012; P. subamabilis
